Tv service part 4

DEFECT: NO SOUND POSSIBLE HINTS : 1.) check first your speakers, it is usually the most common culprit after repairing a television with power supply problem based on my repair experience. 2.) Check if the supply voltage for audio ampifier is present, if not check the line. 3.) If the supply voltage is present, try doing a hum test by touching the input of the audio IC, refer to the datasheet to find the input pin of the IC. Replace the audio IC if everything is done
